[AIMIGRAPHX-1003] Add warnings for dim and value not set

[eddieliao]

Motivation

Warn the user when input dimensions or input values are not set, with the goal to improve usability.

Technical Details

Batch size is excluded from the warnings as it is common in most models and the default value of 1 typically works.

Changelog Category

Add a CHANGELOG.md entry for any option other than Not Applicable

• • Added: New functionality.
• • Changed: Changes to existing functionality.
• • Removed: Functionality or support that has been removed. (Compared to a previous release)
• • Optimized: Component performance that has been optimized or improved.
• • Resolved Issues: Known issues from a previous version that have been resolved.
• • Not Applicable: This PR is not to be included in the changelog.

Pull request overview

Adds user-facing warnings to improve usability when ONNX model inputs have unresolved symbolic dimensions or when the driver runs with inputs that were not explicitly provided.

Changes:

• Emit a warning during ONNX parsing when symbolic dimension parameters are unbound (excluding “batch” dims).
• Emit a warning in the driver when program inputs are not explicitly set via fill/load options.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated 4 comments.

File	Description
src/onnx/onnx_parser.cpp	Adds a pre-parse warning for unbound symbolic dimension parameters in graph inputs.
src/driver/main.cpp	Adds a warning when running with inputs that are not explicitly populated (fill/load).
